Let's not forget that the good thing about salary is that it is strongly related to player strength. If you put in an artificial cap on salary however, B3-participants will scramble for skills that are not reflected in salary, so player value at the top end (affordable only to savers, again) will then be determined by skills that are more weakly related to player strength - that is an undesirable artefact. Think of level 25+ drivers with level 15 primaries as the elite of the game, on all 5 positions... this would not be much "basketball" either, inspite of this year's NBA-MVP.
What probably could be done to slow down super-savers is to introduce negative interest on a user's cash. In effect, this would imply a softcap on savings, with the level of the softcap depending on the saving rate (i.e. again favouring small countries). The fan survey already has a bit of this, but probably too little. Not sure whether von Hayek would have liked that though ;-)
I don't really know, he didn't study BB economý :D
Well there are some C's and PF's who are around 12-13 driving and yes, they sell for elite prices at this moment and without salary cap.
And yes, it will continue to be something good that salary is related to player strength. But that's not an issue.
I mean, right now you do see that most top managers do fight to get the more complete players on the market and that's not issue, and yes, right now top managers do seems to be looking for players with a lot of skills not reflected in salary for every level of player salary segment. And that's a good thing, since those player do require more training time and thus, are *better* than the others. In Basketball terms, they are also good.
If what you try to say is that B3 participants will push the price of very complete players too high, I'll say that's already happening but not only B3 long-term-planner-participants are the ones doing it.
The issue I see with the negative interest is that it will benefit small country managers a lot when compared when big countries (like you pointed out yourself). Anyway, the idea of negative interest rate do have benefits in his own right because it will slow down the savings that small countries are now getting, this will help a little to make a more *democratic* market. So, even if is not a really great idea to help solve the B3 problem, it does have arguments to be used for another purpose.
